Step-by-step explanation:
Half of the animals are cats. If they take in 5 cats, then the total number of animals is 2×5 = 10.
If they take in 8 animals, the number of cats is ½ of 8 = 4.
If they take in 6 cats, then the total number of animals is 2×6 = 12.
If they take in 16 animals, the number of cats is ½ of 16 = 8.

Step-by-step explanation:
Meals are cooked in a process with two resources. The first resource has a capacity of 28 meals per hour. The capacity of the second resource is 24 meals per hour. The first resource has 9 workers and the second resource has 8 workers. Demand for this process is 31 meals per hour. Wages are $24 per hour. Instruction: Round your answer to four decimal places. What is the cost of direct labor (in $s)? _____________ per unit
Answer:
The cost of direct labor (in $s) is $7.85 per unit.
Step-by-step explanation:
First resource total wages per hour = Number of workers in first resource * Wages per hour = 9 * $24 = $216
Second resource total wages per hour = Number of workers in second resource * Wages per hour = 8 * $24 = $192
Total wages of the process per hour = First resource total wages + Second resource total wages = $216 + $192 = $408
Cost of direct labor per unit = Total wages of the process per hour / (Capacity of first resource + Capacity of second resource) = $408 / (28 + 24) = $7.85
Therefore, the cost of direct labor (in $s) is $7.85 per unit.
Determine whether the lines x+ 7y= −3 and y = 7x + 25 are parallel, perpendicular, or neither. Justify your answer by showing all the needed work.
Answer:
perpendicular
Step-by-step explanation:
Rewrite the equations
y = (-1/7)x - 3/7 -- L1
y = 7x + 25 -- L2
Slope of L1 x Slope of L2 = -1/7 x 7 = -1
As a result, the two lines are perpendicular

33) Name four congruent angles that are acute angles.
Answer:
Angles 2, 3 and 6,7 are acute angles
Answer:
∠2≅∠3
∠6≅∠7
∠3≅∠6
∠2≅∠7
Step-by-step explanation:
Hello There!
Acute angles have to have an angle that measures less then 90 degrees. This can simply be determine by looking at the angle and seeing if it makes a smaller angle or a larger angle
∠2 and∠3 are vertical angles which have congruent measures
∠6 and∠7 are also vertical angles
∠3 and∠6 are alternate interior angle which are can be known for being congruent
∠2 and ∠7 are alternate exterior angles which are also congruent
so angles 2, 3, 6 and 7 are all congruent

If the ratio of areas of two similar triangles is 9 : 4, then the ratio of its corresponding sides is .
(a) 9 : 4 (b) 4 : 9 (c) 3 : 2 (d) 81 : 16
Answer:
The answer is c
Step-by-step explanation:
If the area of the two triangles are similar, then Area of ∆ 1 : Area of ∆ 2 =
(Side of ∆ 1)² : (Side of ∆ 2)²
____________________________
Since the area of each triangle is equal to the corresponding side squared.
Area of ∆ = (Side of ∆)² →
√(Area of ∆) = Side of ∆ →
Side of ∆ = √(Area of ∆).
Therefore:
9 : 4 → √9 : √4 = 3 : 2

The members of a basketball team are selling T-shirts during spirit week. The cost is $20 for the design and $1.50 to print each T-shirt. The cost, y, to print x T-shirts is y=1.5x+20. Interpret the slope and the y-intercept.
Answer:
Slope of 1.5 means that the printing of each new t-shirt is of $1.50.
The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.
Step-by-step explanation:
Equation of a line:
An equation of a line has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the increase in y when x increases by 1.
b is the y-intercept, which is the value of y when x = 0.
The cost, y, to print x T-shirts is y=1.5x+20.
Slope of 1.5 means that the printing of each new t-shirt is of $1.50.
The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.

a normal distribution has a mean of 56 and a standard deviation of 8. Find the percentage of data values that are in the given interval. Use the curve to aid you.
Answer:
12) Between 40 and 64 = 0.815
13) Between 32 and 40 = 0.0235
14) Between 56 and 64 = 0.34
15) At most 56 = 0.515
16) At least 72 = 0.025
17) At most 64 = 0.855
Explanation:
To answer this, we will convert each of the values into their standardized form to make this easier.
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ
x = Each value
μ = Mean = 56
σ = Standard deviation = 8
12) Between 40 and 64
For 40,
z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2
For 64
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
So,
Between 40 and 64 = Between -2 and 1
From the curve, noting that the central point is the mean, with standard score of 0, the lines before it move in step of 1 standard deviation towards the negative side, that is, -1, -2, etc. And the lines before the central point move towards the positive side, that is, 1, 2, 3, etc.
So,
Between -2 and 1 = 0.135 + 0.34 + 0.34 = 0.815
13) Between 32 and 40
For 32,
z = (x - μ)/σ = (32 - 56)/8 = (-24/8) = -3
For 40,
z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2
So,
Between 32 and 40 = Between -3 and -2 = 0.0235
14) Between 56 and 64
For 56,
z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0
For 64,
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
Between 56 and 64 = Between 0 and 1 = 0.34
15) At most 56
For 56,
z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0
At most 56 = At most 0 = 0.0015 + 0.0235 + 0.15 + 0.34 = 0.515
All the regions before z = 0)
16) At least 72
For 72,
z = (x - μ)/σ = (72 - 56)/8 = (16/8) = 2
At least 72 = At least 2 = 0.0235 + 0.0015 = 0.025
(All the regions from z = 2 to the end)
17) At most 64
For 64,
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
At most 64 = At most 1 = 0.0015 + 0.0235 + 0.15 + 0.34 + 0.34 = 0.855
(All the regions before z = 1)

Step-by-step explanation:
This question was linked from another one regarding the lengths of the cubes, you can find it here: https://brainly.com/question/22396279
That question gave you the ratio of the lengths, which is [tex]\sqrt{2} :1[/tex]. Now in geometry, a general rule about solids is that if they are similar, the ratio of their volumes is the cube of the ratio of their edges. In a cube's case, every single cube known to mankind is similar as all the edges are the same length.
So the ratio of volumes would be [tex]\sqrt{2} ^3:1^3[/tex], which can be simplified as [tex]2\sqrt{2} :1[/tex].

Show your work: x - 8 = 12
Answer:
x = 20
Step-by-step explanation:
x - 8 = 12 Add 8 to both sides
x -8 + 8 = 12 + 8 Add -8 and 8; add 12 and 8
x = 20
Answer: x=20
Step-by-step explanation: Just do 12 + 8, addition is the opposite of subtraction so if you need to find the answer just do it backwards, 12 + 8 = 20. Hope this helps

The groups of values plugged into the TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly are,
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.
The correct option is C.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
Given:
TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly.
Then,
N: The overall amount of payments. Calculating this is simple if you multiply the P/Y by the number of years.
I%: Interest rate per year. Enter this rate as a percentage at all times!
Present Value, or PV: This is the sum of your investment or the loan.
PMT: The sum due.
Future Value (FV): This is your desired level of savings or, if you are calculating loans, your projected loan balance at maturity.
P/Y: The quantity of payment intervals per year.
C/Y: The quantity of compounding cycles each year.
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END
Therefore, N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.
